Pickles Put in Packages of Transparent Rubber (Jul, 1940)

Pickles Put in Packages of Transparent Rubber
Pickles, packaged in envelopes of a transparent rubber product, have been introduced by a leading American food packer. The water-tight container, which is protected by a cardboard box, holds neatly arranged sweet pickles which are packed in fluid just as when they are sold in glass bottles. Besides increasing the attractiveness of the commodity, the new method of packing is reported to eliminate bottle breakage and to reduce the weight of the containers.

I think this is one of those products, like catsup, where people buy according to a very specific idea of what the package should look like and so it never caught on.

Also, that scene from ‘The Graduate’ would have been a bit odd:

Mr. McGuire: I want to say two words to you. Just two words.
Benjamin: Yes, sir.
Mr. McGuire: Are you listening?
Benjamin: Yes, I am.
Mr. McGuire: Transparent Rubber.
Benjamin: Just how do you mean that, sir?
